Background technique
Current atmosphere pollution makes a big impact to people's lives health, National Environmental Protection Agency's requirement Industrial Stoves,
The flue gas of the generations such as coal-burning boiler reaches flue dust minimum discharge.The more excellent technique of smoke gas treatment at present is bag-type dust and subsequent
Wet desulphurization, dust content can be down to 30mg/Nm after bag-type dust3Hereinafter, flue gas is through wet desulphurization in the device still having
Flue dust goes up not down behind absorption tower, and reason is that in neat stress that flue gas discharges after wet desulphurization with a large amount of droplet.
Though being equipped with demister in the absorption tower of the prior art, effect is bad, cannot separate removal small dust and droplet, cause to discharge
Neat stress in dust concentration it is high, some there is also chimney and float rain phenomenon, seriously polluted atmospheric environment.
A kind of double helix bundled tube demister that Chinese patent (application number 201520902871.2) is mentioned, double helix demisting
Blade is installed at double helix bundled tube demisting pipe smoke inlet, the neat stress containing a large amount of droplets exists around spiral middle shaft rotation
Flue gas flow rate is improved in double helix bundled tube demisting pipe, flue gas forms violent centrifugal movement, mist along double helix demisting blade
Drop is contacted with the moisture film on double helix bundled tube demisting inside pipe wall and is captured.The mist eliminator flushing facilitates, is not easy to plug, structure
Simply, resistance is small, thus use and maintenance is at low cost, saves the energy, manpower, but the double helix bundled tube demister of single-stage will guarantee
The requirement that smoke dust discharge concentration reaches ultralow still has certain difficulty.
Summary of the invention
The purpose of the present invention is to provide it is a kind of it is reliable for operation, effect stability, energy consumption is small, cost performance is high, easy for installation, energy
Realize the multistage bundled tube demisting deduster that minimum discharge requires.
In order to achieve the above object, the present invention includes demisting deduster frame, helical bundle formula demisting dust removing tube and flushing
Water system.The demisting deduster frame, which is welded in, to be absorbed in tower shell, and helical bundle formula demisting dust removing tube is installed vertically on suction
It receives on the demisting deduster frame in tower.
Multistage bundled tube demisting deduster of the invention is equipped with 2 ~ 4 grades, between every level-one demister between be divided into 1.2m ~
2m。
One layer of flushing water system is set above every grade of demister of multistage bundled tube demisting deduster of the invention, rinses water system
End unite in dendroid distribution.
Helical bundle formula demisting dedusting bottom of the tube described in multistage bundled tube demisting deduster of the invention is equipped with helical-blade
Piece, the helical blade quantity of each helical bundle formula demisting dust removing tube are 2 ~ 20.
The helical bundle formula high 500 ~ 1200mm of demisting dust removing tube described in multistage bundled tube demisting deduster of the invention, directly
250 ~ 600mm of diameter.
Each helical bundle formula demisting dust removing tube described in multistage bundled tube demisting deduster of the invention can be achieved only
Vertical installation and removal.
Multistage bundled tube demisting deduster series of the invention is determined to determine by dust removing effects.
The advantages of multistage bundled tube demisting deduster of the invention, is:
1, the multistage bundled tube demisting deduster of the present invention has the function of self-cleaning, will not block, greatly reduce
The dosage of flushing water；
2, the multistage bundled tube demisting deduster of the present invention is easy for installation, and scene does not have plastics welding workload；Single installation,
Crane is not needed, structure is simple, and convenient for installation and maintenance, demisting deduster frame plate may be used as internal overhaul platform, operational effect
Stablize；
3, the multistage bundled tube demisting deduster installation of the present invention quickly, after putting on hole, puts on bolt；
4, the multistage bundled tube demisting deduster replacement of the present invention is convenient, individually can independently replace；
5, the multistage bundled tube demisting deduster of the present invention has super large actual internal area, does not generate fouling and blocking；
6, the multistage bundled tube demisting dust remover resistance of the present invention is low, stable；
7, the multistage bundled tube demisting deduster construction cost of the present invention and operating cost are cheap, possess very high cost performance.

Specific embodiment
The present invention is further elaborated below in conjunction with attached drawing:
Embodiment 1: the demisting deduster frame 3 in figure welds together with tower wall is absorbed, and plays support helix bundled tube and removes
The effect of mist dust removing tube 4, demisting deduster frame 3 make helical bundle formula demisting dust removing tube 4 is vertical to be installed in absorption tower.Work as cigarette
Gas can generate acceleration when entering the helical blade 4-2 of first order helical bundle formula demisting dust removing tube 4, form strong rotation, add
Droplet in fast flue gas is contacted with the liquid film on demisting dedusting tube cylinder 4-1 inner wall, is promoted drop and flue dust captured, is enhanced
Demisting dust removing effects.The movement of flue gas rotating turbulence makes the liquid film of demisting dedusting tube cylinder 4-1 inner wall along demisting dedusting tube cylinder 4-1
Inner wall moves upwards；Drip ring 4-4 blocks liquid film, so that its aggregation is formed drop and drips downwards, then flows along helical blade 4-2
Under, flushing is formd to helical blade 4-2, is played the role of self-cleaning.1 end of water system is rinsed to be distributed in dendroid, and
Multiple flooding nozzles 2 are installed, 1 height of water system is rinsed with absorption tower diameter adjustment, flushing water can be made equably to cover each
Helical bundle formula demisting dust removing tube 4.It is further that the droplet and flue dust not removed enter second level helical bundle formula demisting dust removing tube 4
Removal.
In embodiment 1, absorption tower diameter is 4 meters, and every grade of bundled tube demisting deduster uses 37 high 900mm, diameters
For the helical bundle formula demisting dust removing tube 4 of 450mm, drip ring 4-4 outer rim is regular hexagon, helical bundle formula demisting dust removing tube 4
Using cellular compact arrangement, the spacing between two-stage demister is 1.4m, the helical blade of helical bundle formula demisting dust removing tube 4
4-2 uses the double-spiral structure of two panels, rinses water system 1 and is located above every grade of demister at the position 1.25m.5 internal diameter of manhole
800mm is installed by manhole 5, is replaced helical bundle formula demisting dust removing tube 4 in which can be convenient.According to actual motion needs,
The first order is rinsed water system every 4 hours and is rinsed 30 minutes, and the second level is rinsed water system every 24 hours and rinsed 15 minutes, absorption tower cigarette
Gas velocity 2.75m/s, 5.12 m/s of flue gas actual flow velocity in double helix bundled tube demisting dust removing tube 4.Measurement through actual motion
Statistics indicate that smoke dust discharge concentration is lower than 5mg/Nm3。
Although the present invention has been described by way of example and in terms of the preferred embodiments, embodiment and attached drawing be not for limiting the present invention,
It is any to be familiar with this those skilled in the art, without departing from the spirit and scope of the invention, it can make various changes and retouch from working as, but equally exist
Within protection scope of the present invention.Therefore protection scope of the present invention should be subject to what claims hereof was defined.
